1'0 (6 It'll/0772, it may concern.-

Be it known that I, FRANK W. BRAINERD, a resident of Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in \Vire-Barbing Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention is an improved wire-barbing machine adapted to themanufacture of various forms of barbs, and so constructed that it wrapsboth ends of the barb about the main wires simultaneously.

The form, construction, and operation of the machine are fully explainedand described in the following specification,and shown in theaccompanying drawings, in which- Figure l is a plan of the machine; Fig.2,a side elevation thereof, looking in the direction indicated by thearrow 0, Fig. 1, the cutting mechanism being removed, and also all thatpart of the machine outside of the line a y,

Fig. 1.; Fig. 3, a front-elevation of the machine, looking in thedirection indicated by the arrow 0, Fig. 1, that part of the machine infront of the line :r i, Fig. 1, being removed; Fig. 4, a centralvertical section (through the line of the main wires) of thewire-supporting spindle and the sleeves mounted thereon; Figs. 5, 6, and'7, front elevations of the spindle and sleeves, showing successivesteps in the wrapping of a barb; Fig. 8, a top view of the sleeves andspindle, showing a barb-wire fed between the main wires and ready forwrapping; and Fig. 9, a side elevation looking in the directionindicated by the arrow 0, Fig. 6, showing the sleeves and spindle and acom pleted barb formed on the main wires.

In these views, A is the bed of the machine; 13, the main shaft, towhich power is applied by means of the pulley G; and B, a side shaft atright angles to the main shaft and connected therewith by miter-gears.On the main shaft is rigidly mounted a cam, G, which actuates theknife-carrying lever It, and on the shaftB are mounted two eams,O C,which communicate motion to the two vertically-reciprocatingsegment-carrying levers D D, respectively, as hereinafter set forth.Near the (N0 model.)

center of the bed is a stationary post or support, J, bolted to the bedand supporting a cylindrical spindle, Z, which is either keyed to thepost, as shown in Fi 4, or formed integrally therewith. The spindleextends forward from the post a sufficient distance to make room for theother working parts, and its axis is a horizontal line parallel to theside shaft,]3. Thelspindle is longitudinally pierced by two perforationsfor the passage and support of the two main wires 20 w to be barbed.

On the spindle Z is mounted a sleeve, L, provided with a pinion, I,which lies imme diately in front of the post J and on the sleeve L ismounted a second sleeve, M, provided with a pinion, I. which liesimmediately in front'of the pinion I. The sleeve L turns freely on thespindle Z, and the sleeve M turns freely on the sleeve L, and the frontfaces of the spindle and the two sleeves are flush. The sleeve M isjournalcd in a post, J, bored out 'to receive it, and bolted to the bedof the machine.

The construction and relation of the parts are such that the sleeve Lmay be slipped over the spindle, the sleeve M over the sleeve L,

and the bearing in the post J over the sleeve M, and upon bolting thelastnamed post to the bedrit serves to support the sleeves andspindle-and also to prevent longitudinal motion of the sleeves on thespindle. The pinion 1 engages with a segmental gear, K, and the pinion Iwith a second segmental gear, K, the segments being formed integrallywith two vertically-reciproeating levers, D D, pivoted on asuitably-supported shaft, T. The outer ends of the levers are providedwith anti-frietion rollers a a, the first-named roller, a, resting onthe upper face of the cam 0, already mentioned, while the other roller,a, rests against the lower face of the cam 0. Suitable springs, S S,hold the rollers constantly in contact with the surfaces of therespective cams, and the rotation of the shaft B thus imparts verticalreciprocal motion to the levers D D and segments K K. The cam C forcesthe segment K upward and rotates the sleeve M in the directionindicatedby the arrow on its face in Fig. 5, and the cam G forces thesegment K downward and rotates the sleeve L in the opposite direction,as indi-' cated by the arrow on its face in the same figure. The innersleeve, L, is provided with an ordinary wrapping-pin, N, set in itsfront face, and the outer sleeve, M, is provided with a wrapping-finger,N, whose base is rigidly attached to the outer edge of the face of saidsleeve, while its point lies nearer the main wires and in front of theface of the sleeve L. (See Fig. 5.) The space between the face of thesleeves and spindle and the finger N is sufficient for the pin N and theend of the barb wrapped by said pin to pass under the finger withoutstriking. (See Fig. 8.)

At the side of the bed opposite the shaft 13 isa suitable barb-feedingmechanism adapted to feed a barb-wire between the main wires and infront" of the sleeves and spindle, and between the barb-feeding deviceand the main wires is acutt-ingmechanism consisting of one stationaryknife attached to the bed and one movable knife attached to the rockinglever B, which is actuated by the cam C, as hereinbefore set forth.

As the feeding and cutting devices shown are old, no particulardescription of them is necessary, and this is especially true since theyare both shown and described in the patent of D. O. Stover, of May 29,1883. No mainwire feed is shown, but any suitable intermittent fecd maybe used, the main wires being fed in the direction indicated by thearrow 0, Fig. 1.

The operation of the machine in making a barb is as follows: The sleevesL M and the pin N and finger N being in the positions shown in Figs. 5,8, the barb-wire w is fed between the main wires 1010, in front of thesleeves and spindle and under and in contact with the pin N and thepoint of the finger N. Immediately after the feeding of the barb thesleeve L is rotated four hundred and fifty degrees, or one andone-fourth revolution, in the direction indicated by the arrow on itsface in Fig. 5, wrapping the free cndf of the barb to the position shownin Fig. (5. Atthe instant when the sleeve L has rotated one hundred andeighty degrees and the free end of the barb is in the position shown indotted lines in Fig.6, the barb is severed by'the cutting device, andthe sleeve M rotates two hundred and seventy degrees in the directionindicated by the arrow on its face in Fig. 5, wrapping the sevcred end10 of the barb to the position shown in Fig. 7. In other words, the freeend f of the barb is wrapped one hundred and eighty degrees, and bothends are then wrapped two hundred and seventy degrees at the same timein opposite directions, thus completing the barb. The barb shown is oneto whose manufacture this double-sleeve device is especially adapted;but it is evident that it maybe used in the making of other barbs whichvary from this one only in the number of degrees through which therespective ends are wrapped. In

the making of any barb both sleeves may begin to wrap at once, ifdesired, or they may commence wrapping at any desired interval of time.I think it best, however, for the sleeve which has the greater wrap tomake to cominenceiirst and rotate through an are equal to the differencebetween the wraps to be made by the two sleeves, respectively. At thispoint the other sleeve should begin wrapping, and both should continueuntil the completion of the barb. If found necessary, the wrapp ngfingerN may be provided with a lip PIOJCCting downward in front of the barb,as shown in dotted lines in Fig. I have found that a slight groove inthe end of the finger is sufficient, but the depending lip might giveadditional security against the escape of the barbwire. In some forms ofbarbs the wrap is nearly all made from the free end, which musttherefore be longer than the end f shown in these drawings. In suchcases the base of the finger N may extend out beyond the edge of theface to which it is attached, in order to permit the free end to passunder it without striking, as indicated by dotted lines in Fig 7. It canbe thus extended without interfering with the other parts of themachine, since the stationary knife is in front of the barb-wire, in theposition shown by dotted lines in Fig, 8, and the finger N will pass inrear of the-knife, no matter how much lateral extension it may have.

I am aware that a stationary spindle longr tndinally perforated for thepassage of two main wires is a common element in wire-ba rbing machines,and that a single sleeve rotating 011 a spindle is old in the art. It isalso true that the cam and segment mechanism used to rot-ate either ofthe sleeves shown in these drawingshas no novelty; and I. do nottherefore claim any of these features; but, Having described myinvention, what I claim as new, and desire to secure by Letters Patent,is 1. In a wire-bathing machine, the combination of a stationarymain-wire-supporting spindle, a sleeve rotating freely on said spindle,a second sleeve rotating freely on said firstmentioned sleeve, wrappingdevices attached to the front faces of said sleeves, respectively,

and means, substantially as shown and de= scribed, for rotating saidsleeves. 2. In a wire-barbing machine, the combination of a stationaryspindle longitudinally perforated for the passage and support of twomain wires, an inner sleeve rotating freely on said spindle, an outersleeve rotating freely on said inner sleeve, suitable wrapping devicesattached to the front faces of said sleeves, means for feeding abarb-wire across and between said main wires in front of said sleevesand in contact with said wrapping devices, means for severing said barbwire between the feeding mechanism and the main wires,and means forrotating said sleeves, respectively, whereby bot-h ends of the severedbarb are wrapped about said main wires at the same time.

3. The combination of the spindle Z, sleeve I structed and combinedsubstantially as shown 20 L, rotating on said spindle, sleeve M,rotating on said sleeve L,wrapping-pin N, attached to the front face ofthe sleeve L and adapted to wrap the free end of a barb-wire about themain wires and against the face of the spindle, and the wrapping-fingerN, having its base attached to the front of the sleeve M at a suitabledistance from the center to permit the free end of the barb to passunder, it without striking, while its point is sufficientlynear thecenter to adapt it for wrapping the severed end of the barb about themain wires, substantially as shown and described,and for the purpose setforth.

4. The combination of the spindle Z, the sleeve L, mounted on saidspindle, sleeve M, mounted on said sleeve L, and bearing J, in whichsaid sleeve M is journaled, all conand described, and for the purposeset forth.

5. The combination of the spindle Z, sleeves L M, pinions I I, mountedrigidly on said sleeves, respectively, geared segments K K, engagingwith said pinions, respectively, oscillating levers D D, formedintegrally with said segments, respectively, and cams G Qantnating saidlevers, respectively,whereby said sleeves are rotated reciprocally,substantially as shown and described, and for the purpose set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
